Philip Jones Griffiths, Boy Destroying Piano, 1961

This image shows the city of Pant-y-Wean, once voted the most beautiful city in South Wales, not destroyed due to mining. The photographer shot at a lower angle than the boy to make him look grandiose as he prepares to drop the rock on the piano. It is a representation of the beauty in destruction, a piano which plays a beautiful tune now stripped to its elements playing its last notes as the boy is about to completely demolish it the way this once beautiful city has been destroyed by man. The boy v.s man is a reflection on the past and future, the past being the boy, a symbol of innocence, who is performing the act of man, destroying something beautiful.  Griffiths uses good contrast between the boy and the gray of the background to see all the pieces of lumber scattered across the grounds. 

Landscape

Original

In this image I increased the contrast in the snow and water. I used the burn tool to darken the tones in the sky. I sharpened the image to make the ripples in the water more crisp.

Original

In this image I originally kept it in color because I thought it had a lot of good shadows. After looking at it for a little while I became with the desaturated winter colors. When I changed it to black and white I thought it had a lot more impact because of the different tonal range.

Fishing, Celebes Sea

Photographed by Liang Huan Chuan

The photographer used a wide angle lens to photograph this image. He may have used a low ISO and a fast shutter speed to freeze the waves in motion. There is a good rule of thirds in the division between clouds, sky and water moving vertically, and between the fisherman boat, the hut, and the sky from foreground to background. The rich blues of the sky gradient and the clarity in the water make the composition more effective. 

Stop Motion

Original: Focused lens on the bowl of water. Used the stop motion technique to capture the falling of the caps. 

Edited: Used the adjustments brush to desaturate the background and give a type of halo effect to the hand and caps. Sharpened the image to enhance highlights and shadows of the hand and bottle caps.

2012 Olympics Commentary

Photographer: Unknown
In this 2012 Olympics image of rhythmic gymnastics, the photographer used the technique of stop motion to literally freeze the gymnast in mid air. He used a fast shutter speed to stop the movement. He may have used a low F-stop to blur out the background and keep the gymnast in focus. He used a long frame to emphasize the length of her legs across the image. There's tension between where her toe nearly touches the hoop and the perfect form of her legs and bend of her back.
